Abstract

The invention relates to a multi-wavelength nanometer laser system implementation method. An existing technology is complex in process, low in flexibility and not high in controllability. Different laser wavelengths are achieved on the basis of the multi-layer spherical shell nanometer optical and plasma mode interaction mechanism through a multi-layer spherical shell nanometer laser device unit and different geometrical parameter multi-layer spherical shell nanometer laser device units, flow control is conducted on nanometer laser device micro-passageways with different wavelengths through the combination with the electrorheological effect, multi-layer spherical shell nanometer laser device systems with different laser wavelengths are mixed, and a dynamic nanometer laser device system is obtained. The multi-wavelength nanometer laser system implementation method has the advantages that the nanometer laser device units with the multi-layer spherical shell structures are arranged, the laser devices are simple in structure, the implementation process is simple, the nanometer laser device structure does not need fixing bases, the multi-wavelength nanometer laser device system can be obtained, the system distribution controllability is high, distribution is flexible, and the number of the nanometer laser devices with different wavelengths can be dynamically controlled.

[0002] technical background [0003] A laser is a device that uses the principle of stimulated radiation to amplify or oscillate light in certain excited substances. It usually consists of three parts: an excitation source, a working medium and a resonant cavity. The excitation is that the working medium absorbs external energy and excites to The excited state creates conditions for realizing and maintaining the inversion of the number of particles; the metastable energy level of the working medium makes the stimulated radiation domina...

Problems solved by technology

Although this prior art has certain advantages, there are essential deficiencies: First, the use of coaxial multi-layer cylindrical shell structure has a complex structure, and there are many parameters with high precision requirements on the micro-nano structure, and the parameter values ​​are diverse, resulting in The manufacturing process is difficult and the maneuverability is inflexible; secondly, the nano-laser structure needs the substrate as a support, increasing the components of the nano-laser increases the size of the device as a whole, and the laser structure and the substrate are fixed to each other, so it is impossible to realize flexible manipulation of the laser; realize nano-laser It is difficult to control the dynamic position of the laser, and the distribution flexibility is poor. In essence, the prior technology cannot realize the dynamic nano-laser system, the different dynamic movements of the nano-laser, and the dynamic change of the number of nano-lasers with different wavelengths.
